To all 'when'. fit may concern.'

Be it known that l, JOHN E. REDIN, u citizen of the United States, residing at Rockford, in the county of Winnebago land State of illinois, have invented a new and useful Latch, of which the following is a speciiicetion. l'

The present invention` appertains generally to latches, und relates more particularly to furniture latches. 1

it is the object of Vthe present invention to provide a novel und improved latch for the drawers, doors and other-,moving parts of furniture, such as desks, cabinets, and. other house und office furniture.'

Another object of the present invention is to-provide a. latch of that character which shell be readily applicable to various objects, undy without the necessity of screws, nails or othersecuring members being en ployed. y

A further object of the present invention is to provide e device of the nature indicated which shell be comparatively simple, du roble, substantiel, compact und inexpensive in construction, es Well es serviceable, convenient and eflicient in its use'.

vVith the foregoing und other objects in view, `which will be apparent as the nature ofthe invention is better understood, the present invention resides in the combination end arrangement of ports and in the details ol construction hereinafter described and claimed, it being understood that changes in' the precise embodiment of the- 'invention herein disclosed con be made within the scope what is claimed withoutA departing troni the spirit'of the'invention. p

The invention has been illustrated in several of its preferred embodiments, in the accompanying drawing, wherein similar reference characters have been employed to denote corresponding parts, und wherein Figure l is o section of one forni of the device, the section being teken appl-ourl mately on the central or medien plane. F ig. is s section-.1l detail taken on the line 2-2 oi' l. Fig. 3 is u, fragmento] detail of the forni illustrated in Fig. il. Fig. -l is a view similar to Fig. .l of n second inodilicfr tion. Fig. 5 isn` view similar to Figs. l and l, of anothervariation. Fig. (i is e. view similar to Fig. l, illustrating another modification. Fig. 7 is u rear view of the modi isi om internes in rig. e. rig. e is t sectional view taken on the line 9--9 of Fig. `6.

' ln currying out the invention, reference being had in detail tol Figs. l, 2, und 3, there is provided a latch bolt tube l, und .1 plunger tube 2, which are adapted to intersect each other when applied to "an object. These tubes and 2 are preferably of like diameter, the tube 2 being provided adjoining its inner or lower end, with rectangular openings 3 in its opposite sides, und opposite sides of the tube l being Hut as ut 4, from the rear or inner end of the tube 1 to u point short loi" its outer or front end to provide the shoulders The rear or' inner end of the bolt tube l is adapted to be inserted through the openings 3 of the tube '2, the tubes being :it right angles with respect to euch other, und the la't sides l of the` tube l permitting the said tube to bepassed through the openings or slots 3 of the tube 2 in the manner specified. lVhen. the tube l is inserted tbrdhgh the tube 2, the shoulders 5 nre adapted to sent, against the tube 2' at the edges of the respective opening 3, to limit the inward movement of the tube l.

"lf'be tube lis provided with un upper longitudinal slot (3 within the tube und with n sinnlnr lower slot 7, the tube 2 being provided at its rear side with n longitudinal slot 8 intersecting the respective opening 3, and extending from the' lower or inner end of the: tube 2 to u point slightly above the respective opening The 'latch bolt 9 is preferably of circular cross section sofas to lit snuglyin the tube l` with its inner end spaced from the inner end vof the tube und with its outer end dapted to 'beprojected from and retracted into the forward or outer end of the said tube. The latch bolt 9 is provided with an opening or slot l0 adjoining the tube 2 and e coiled wire spring 11 is`y housed within the inner Y or rear portion ofthe tube l in back of the hitch bolt 9 to project or shoot the saine. rl`he rear or inner. end of the tube 1 is prei"l erubly closed to provide u sent orthe respective end of the springll, although any other suitable seat or bearing )"or the spring muy be provided zit-the inner end of the said tube. the. other end of 'the spring bearing against the inner end of .the latch bolt to create a tension thereaginst.

A plunger or actuating member 12 is slidably disposed lWithin the tube 2, the seid plunger being preferably stamped from a bar or plate of suitable sheet rrietal or other material, although it may be otherwise ash ioned. The plunger 12 is provided with the lower inclined end 13 providing a cam, the tip of which passes through the upper slot 6 of the tube 1 and partially enters :the opening or slot 10 of the latch bolt. At the heel of the inclined or-cam end 13 of the plunger, the same is provided with a shoul der or stop 14 adapted to strike the upperor outer end of the slot 8 when the plunger is moved upwardly or outwardly, as seen in Fig. 1. The shoulder or stop 14 is adapted to move within the slot 8, it being noted that the said slot extends to the respective end of the tube 2 to permit of the convenient insertion of the plunger 12 prior to the engagement of the tube 1 through the tube 2.

A suitable wooden or other knob or finger hold `15 is secured over the outer or upper end of the tube 2, this being readily accomplished by threading the knob 15 over the tube 2.

In applying the said latch to an object, such as illustrated at 16, in Figs. 1 and 2, in order that the object or part 16 may be latched to an adjoining object or part 17 a bore 18 is drilled into the part 16 away from the part 17, and a second bore 19 is drilled into the part 16 at right angles to the 'bore 18, ,and so as to intersect the last mentioned bore. The part 17 is provided with a keeper or socket 20, for the reception of the latch bolt 9 when it is projected by the spring 10. The tube 2 with the plunger 12 inserted therein, is inserted into the bore 19 so that the openings 3 register with thebore 18, and the tube 1 is then inserted into the last mentioned bore, so as to pass throu h the openings 3. The spring and latch olt may be introduced into the tube 2 either before or after the insertion of the tube 1 within the bore 18, the tip of the plunger 12 being adapted to engage within the slot or o ening 10 of the latch bolt. When the tu e 1 of the part 16 registers withlthe keeper or socket 2O of the part 17, the latch bolt 9 will be projected into the keeper or socket by the spring l1, the plunger 12 being in raised position, as seen i Fig. 1. By pressing the 'plunger 12 inwardly or downwardly, the cam 13 will ride against the inner end of the slot or opening 10 of the latch bolt, .and con'- sequently, the latch bolt will be retracted from the keeper or socket 20 to'permit the parts 16 and 17 -to separate. It will thus be apparent that the latch bolt may be readily operated through the medium of the plunger 12.

VVhen-the tubes 1 and 2 are inserted in the manner specified. it will be apparent that the tube 1 will lock the tube 2 within the respective bore 19, the tube 1 also being frietionally held in position so that the tubes may be engaged to the object or part 16 vWithout the employment of screws or other securing members.y The tubes are also easily and quickly applied to the object by simply drilling the bores into the object at right angles so that the bores intersect. It is preferable to have the knob 15 tiush with the object 16, although this is not essential.

In the form illustrated in Fig.' 11, the general construction is somewhat the saine as the form above described. The tube 23L is inserted into the bore 19 drilled in the object 16, the tube 1*l being slightly smaller in diameter than the tube 2n adjoining its inner or lower end and being inserted through the openings 3 in the tube. rlhe tube l is provided with the upper and lower slots or openings 6a and 7 1 respectively, within the tube 2 and the tube 2 is provided with the rear longitudinal slot 8 extending from its inner or lower end to a point short of the outer end. v

The latch bolt 9 is hollow and preferably has its inner or rear end open. The latch bolt 9*L is provided with a longitudinal slot 10a in its upper side adjoining its inner end, and a coiled wire/spring 111 is housed within the latch bolt, the forward end or theV spring seating against latch bolt, and the rear end of the spring being engaged by an ear or inger 22a struck inwardly Jtroni the bottom of the tube 1a at the forward en'd of the slot 7a through a 'lower slot 21 provided in the latch bolt.

The spring 11 being under compression presses the latch bolt outwardly or orwardly to project the latch bolt into the proper keeper or socket (not shown).

The plunger 12 2a and the knob 15a which is engaged to the tube and which projects beyond lthe tube, the inner or lower end of the plunger 12EL being provided with, an inclined or beveled portion 13, enters the slot 10 of the latch bolt, so that when the plunger is depressed or forced inwardly, the latch bolt will be retracted inasmuch as the cam 13a works against the inner end of the slot `10ft. The plunger 12 is provided with the shoulder or stop 14C working within `the slot 8a and seated against the outer end of said slot when the plunger is slid outwardly or upwardly Inasxnuch as the form of trated in Fig. t operates in a similar to the and'n2, further description thereof is not deemed necessary, the .tubes 11 and 2 also being inserted in the object in the manner of the tubes 1 and 2 above described.

In the variation illustrated in Fig. 5, the tube 2b is inserted into the bore 19b of the object 16b and the tube 1b is inserted into the bore 18b of the,said object through circular openings 3" .latch illusmanner provided in the tube 2%'.

the #forward end oit" is sudati@ Within the wie forming a cam,\the tip of which form illustrated in Figs. 1

4tube lb is the tube 1 b being preferably. of smaller diameter than the tube 2b.

provided with the upper and lower longitudinal slots or. openings 6b and 7b respectively, while the tube 2* is provided with the longitudinal rear slot 8* intersecting the respect-ive opening 3b. A latch bolt 9b isvslidable snugly within the tube 1,", and is provided with'adiagonalopening or passage l0b therethrough adjoining its rear or inner end. f

The plunger embodies a stem 12b having a' finger piece'24b threaded onto its outer or upper end and working snugly within the knob l5", the lower or inner end of the stem 12b being provided With a circular head 231 working snugly within lthe tube 2b. The head 23h is provided With a depending diagonal finger 13h, the tip of which enters the diagonal opening or passage 10b of the latch bolt, in orderthat when the plunger, or .nger piece 2li thereof, is depressed or forced inwardly the 'latch bolt will be re.- tracted'. The heel of the finger 13b is provided with a shoulder or stop 14h working within the slot 8b. Ears 22h are struck inwardly ifroni the tube 2", a coiled Wire spring 1lb surrounding the stem 12b and terminally engaging the'ears 22 and the finger piece 2LH to normally raise the plunger. to thereby project the latch bolt.

From the tion with Fig. 5, the operation of the device will be clearly apparent without further detailed description.

slightly The In the modification illustrated in Figs. 7,

8 and 9, the general construction is something similar to the forni illustrated in Fig. l. The tube 2d is insertedv into the bore 19d drilled in the object 16f,`the tube ld which lits in the bore 18d being slightly smaller in diameter thanthe tube 2d, and the tube 2d having -circular openings 3dl adjoining its inner or lowerend, through Which-the tube ld is passed. The tube'ld is provided with the upper and lower longitudinal slots 6 and Tdwvithin the tube 2d, and the tube 2d is provided with a longitudinal rear slot 8 intersecting the rear .opening 3, and eX- tcnding to the inner or lower end of the tube 2d. The latch bolt 9 is slidable snugly within the tube l, and is provided with a reduced portion 0 intermediate its ends, and forming a shoulder 9. The reduced portion 9 of the latch bolt provided. with a slot 10, and the tube 1d is provided with instruck ears or lugs 22d entering the lslot lO' ot thc latch bolt at the outer ends of the slots .td and 7d. A coiled wire spring il surrounds thc reduced portion 9 of the latch bolt and is terminally seated against the shoulder 9 yieldingly shoot the latch boi; the free end of the latch bolt, being preferably curved in order that the latch bolt may snap into 'with a bevel 13", th

K inward foregoing, taken in connec' and the ears 22, to-

engagement' with or other object 16d the keeper.

The fiat plunger 12d which is slidable in the tube 2fi is provided at its lower end e tip or nose of the plunger 12d entering the slot l0d of the latch bolt and'passing through the slot 6d of the-tube ld. e plunger l2d is provided withv a stop or lug 14d at the heel of the bevel or cam 13d, which stop or lu 1s closed lor swung toward slidably engages through the slot 8d of thev tube 2d. The pushv button or finger piece 2li is slidable in the mouth or outer end of the tube 2d, and is threaded over the stem or shank 12 of the plunger 12d, whereby theI plunger may be readily pressed or forced to retract the bolt.

The end of the/slot 8d ofthe tube 2d is offset, as at 8', to forni the shoulder 8, against .which the stopor lug 14d is normally adapted to rest, to prevent'thetip or nose of the plunger from disengaging theslot -10d, which would permit the latch bolt to be withdrawn. By springing or twisting the plunger 12d, however, the stop or lug 14d, may be sprung into the offset end 8 of the slot 8", so that the plunger l2d may be slid the keeper when the door 4 upwardly out of engagement with the latch bolt, whereby the latch bolt 9d and tube 1d may be withdrawn from the tube 2d.

From the foregoing taken in connection with the drawing, it will be manifest that various forms of latch bolts may be provided, and that various means may be r0- vided for actuating the latch bolts, it being understood, that the present invention is susceptible of numerous alterations and modiications .within the scope of the appended claims, spirit of the invention.

.Ha-ving thus described the invention, What I is claimed as new is l, Ina latch, a, tube having diametrically opposite openings, a second tube inserted through the said openings, a latch bolt slidab-le within the second tube, the first mentioned tube having a longitudinal slot eX- tending from one end -beyond the said openings, and a plunger slidable in the other end portion of the rst -mentioned tube, and havf ing its inner end operatively engaged With the latch bolt, the plunger having a stop engaging in the said slot to limit the movement of the plunger away from the latch bolt.
